煤制活性炭

Producing active carbon from coal

活性炭是一种多孔性炭素材料,具有很大的比表面积和细孔容积,吸附能力强。根据制造原料的不同,活性炭可分为木质活性炭和煤质活性炭等;根据成品形态的区别,又分为颗粒活性炭、破碎活性炭和粉末活性炭等;根据使用环境的区别,还可以分为气相吸附用活性炭和液相吸附用活性炭等。目前国外活性炭已发展到上千个品种,我国还不到百种。活性炭不仅广泛应用于化工、石油、冶金、医药、食品、染料、国防、制糖和油脂等工业,还大量用于环保和生活用水处理。

this paper concentrates on requirements to raw materials, technological procedure, the structure and features of oven for making active carbon from coal and study on parameters of various type of ovens. Based on the existing production conditions and technology,the requirements to coal are low ash, low sulphur, adequate volatile matter and caking properties, in order to achieve good economic results. This paper also describes experience with making active carbon in small scale in two plants in Shangdong and Ningshia.
